SLAE Problems for Competitive Programming [Tutorial]

Revision en1, by MazzForces, 2018-06-13 12:43:24

Hello Codeforces,

SLAE stands for system of linear equations. Basically, consider we have a set of equations of the form :

a₀·x₀ + a₁·x₁ + a₂·x₂ + ... + a_n - 1·x_n = m b₀·x₀ + b₁·x₁ + b₂·x₂ + .... + b_n - 1·x_n - 1 = n c₀·x₀ + c₁·x₁ + c₂·x₂ + .... + c_n - 1·x_n - 1 = o .....

Note that all

a, b, c..

are arrays belonging to

$\text{[math]}$

and

m, n, o..

are arbitrary numbers

$\text{[math]}$

gauss elimination, #math, xor
